Wireless Routers/Gateways provided by Internet Service Providers (such as Comcast, Time Warner, Road Runner, Charter, etc.):
The routers listed below are provided to customers by their Internet Service Providers (ISPs). Due to the way the Wii console interacts with these routers' firewalls (sometimes called an SPI firewall), it may not be able to connect online, even when using the Nintendo Wi-Fi USB Connector or the Wii LAN Adapter. If you are able to log in and disable the router's firewall (you may need to get a "super user" password from your ISP), you may be able to get the Wii console connected online. If you use an ISP that prevents the firewall or SPI firewall setting from being adjusted, or if you prefer not to adjust the router's firewall, there is a system update that may resolve the console's ability to connect with Nintendo's servers, enabling the use of some online features.
To download the system update to your Wii console, you will need to successfully connect your Wii console online. If your current connection through your ISP-provided router is preventing a connection, you will need to find an alternative online connection, such as taking your Wii console to a friend's house where there is a compatible internet connection. (If this option is not available to you, link here for information on other options.) Once you have connected the Wii console online, the system update will download and install. With this update, you should be able to download any future updates with your own internet connection. If after performing this update you are still experiencing problems, visit http://support.nintendo.com for further assistance.

Nintendo also has this to say about connection problems Hemoglowen...

well, the weird thing is, is ive connected to it before. and now it doesnt let me. and since im at school the free wireless here doesnt allow p2p which would let me play against other players online...

Important Note: It has been our experience that 2Wire routers may require the following changes to enable a stable connection with the Wii console:

Some connection stability and speed issues can be resolved by going to the "Wireless" settings and changing the wireless channel to 1 or 11.
Turning the router's internal firewall OFF. To do this, log into the router's setup utility, and choose the "Firewall" option. Select "View Settings" or "View Details", and then select "Allow all applications."

While we have found that disabling the internal firewall can help with connecting the Wii console online, please note that Nintendo provides this information for our consumers' use. It is up to each consumer to determine what security needs they have for their own networks, and to decide how best to configure their network settings to meet those needs.

I'm kind of chasing Nintendo around in circles Hemoglowen but I may have stumbled onto something.
